Naming Ionic and Covalent (molecular)

Compounds

Metal ions have the same name as the element Sodium atoms sodium ions Aluminum atoms aluminum ions

Nonmetals ions have same root as the element, but add –ide as a suffix Chlorine atoms chloride ions Sulfur atoms sulfide ions

Contain 2 different elementsName the metal ion first, then the

nonmetal ion (with –ide).Use name of a metal with a fixed

chargeGroups 1, 2, 13, 14and Ag, Zn,

Examples:NaCl sodium chlorideZnI2 zinc iodideAl2O3 aluminum oxide

A group of atoms with an overall charge.

NH4+ ammonium OH- hydroxide

NO3- nitrate SO4

2- sulfate

CO32- carbonate

HCO3- hydrogen carbonate (bicarbonate)

Nomenclature of ternary ionic compounds

Contain at least 3 elements Name the nonmetals as a polyatomic ion Examples:

NaNO3

Sodium nitrate

K2SO4

Potassium sulfate

Al(HCO3)3

Aluminum hydrogen

carbonate

Nomenclature of binary ionic compounds

NaHCO3 K2SO4 Ca(CH3COO)2 KCN Fe3(PO4)2

Ca(OH)2 (NH4)2CO3 Zn(NO3)2 Li3PO4 CuNO3

Naming salts composed of the polyatomic ions is the same as with the monatomic anions. Metal name then polyatomic name.

NaOH sodium hydroxide Ba(NO3)2 barium

nitrate

H2SO4 hydrogen sulfate CsNO3 cesium nitrate

KHCO3 potassium hydrogen carbonateNote: the polyatomic anions must be memorized.
